PRIORITY CLAIM

This application claims priority to Chinese Patent Application Serial No. 201610509396.1 filed on Jun. 30, 2016 and entitled “Method and Device for Data Center Management.”

FIELD

Embodiments of the present disclosure generally relate to data center management and more specifically to methods and devices for data center management.

BACKGROUND

As the scale of a data center increases, its infrastructure changes faster than ever. Many factors will lead to changes in data center infrastructure, for example, changes in the infrastructure caused by hardware failure become more frequent. The reliability of the hardware can be measured by a Mean Time Between Failure (MTBF) formula. Given the MTBF, hardware failures are believed to be substantially proportional to the number of hardware devices in the computing environment. Besides, as the update cycle of the infrastructure becomes shorter, the changes in the infrastructure caused by hardware replacement become more frequent.

In another aspect, the expansion of the scale of the data center also sets higher demands for infrastructure management, for example, it is expected that unified management and orchestration of the infrastructure is achieved, and the infrastructure is changed according to the varying workload. However, for example, the Internet of Things (TOT), cellphones or the like make the application workload unpredictable, because predicting the application workload requires a more intelligent approach for datacenter management and orchestration, which increases the complexity for managing the data center.

DETAILED DESCRIPTION OF EMBODIMENTS

The preferred embodiments of the present disclosure will be described in more details below with reference to the accompanying drawings. Although the accompanying drawings show preferred embodiments of the present disclosure, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete and to convey the scope of the present disclosure to those skilled in the art.

As used herein, the term “includes” and its variants are to be read as open-ended terms that mean “includes, but is not limited to.” The term “or” is to be read as “and/or” unless the context clearly indicates otherwise. The term “based on” is to be read as “based at least in part on.” The term “one example embodiment” and “one embodiment” are to be read as “at least one example embodiment.” The term “another embodiment” is to be read as “at least another embodiment.” The terms “first”, “second” and the like may refer to different or same objects. Other explicit and implicit meanings may also be included hereinafter.

Traditionally, manual or semi-manual ways are often used to trace infrastructure and update infrastructure information in a configuration management database (CMDB) or in other storage storing the infrastructure information. The process of manually checking the infrastructure, comparing the differences of the infrastructure, and manually inputting the altered infrastructure information into the database still exists in many data centers. Such process has a low efficiency and will cause manual errors. For example, the error rate can be set to a fixed value, and the occurrences of errors grow with the increase of manual operations. Clearly, as the number of infrastructures requiring manual operations and steps involving manual work required by an infrastructure increase, more errors may be caused.

Some data centers update the above process by introducing semi-automatic ways, for example, by using Radio Frequency Identification (RFID) and Quick Response (QR) codes to describe hardware. However, such a solution works outside the infrastructure and only automates the process of receiving the infrastructure information and updating the CMDB. However, both RFID and QR codes are still manually input hardware by hardware, which cannot fundamentally solve the problem. Furthermore, the manual input stage may also cause errors and take a lot of time. What is worse, the longer it takes to synchronize the mismatched information, the higher the possibility that a risk occurs.

At present, the scale of the data center is constantly growing along with the presence of cloud computing, IOT, artificial intelligence, big data and other new technologies, and the manual operations become infeasible in the production. Therefore, how to automatically trace and update the change in the infrastructure becomes a key requirement of the data center management.

To at least partially solve the above and other potential problems and defects, embodiments of the present disclosure provide a solution for data center management. FIG. 1 illustrates a schematic diagram of a data center management system 100 according to embodiments of the present disclosure. The data center management system 100 can comprise an infrastructure tracing processor 110, a resource profile 120 (also referred to as a resource model 120), hardware management and orchestration software 130, one or more hardware devices 140 (individually and collectively denoted herein using reference numeral 140) and a database 150.

The infrastructure tracing processor 110 can obtain information of the one or more hardware devices 140 used in the data center, identify the one or more hardware devices 140 by matching the obtained information with the resource profile 120, and update record(s) associated with the one or more hardware devices 140 in the database 150 of the data center using the obtained information.

The resource profile 120 can be included in the infrastructure tracing processor 110, and can record identifiable attributes of a plurality of types of hardware devices 140 and other optional information. In some embodiments, the resource profile 120 can be used to identify the one or more hardware devices 140, and describe attributes of the one or more hardware devices 140, such as attributes of the one or more hardware devices 140 in various types of computing nodes, memories, switches or power distribution units (PDU) in the data center. The resource profile instances for the computing nodes, memories, switches, PDUs or the like can be constructed based on the resource profile 120.

An example of a segment of the resource profile 120 is presented as follows:

Name: ABC MAC: CPU:  Count: 2  Family: Intel(R) Xeon(R) CPU E5-2698 v4 @ 2.10GHz DIMM:  Count: XX  Size: XX S/N: P/N: xx-xx-xx-xx ...

As shown above, the resource profile 120 can be text-based. The text-based information of the hardware device 140 is clear in meaning and easy to be processed, so as to achieve better transform in different environments and varying hardware devices 140. Of course, resource profile 120 based on other formats or encoding methods is also feasible in other embodiments.

The resource profile 120 can comprise standard keywords describing general hardware attributes and description keywords describing dedicated hardware attributes. As illustrated above, standard keywords can be keywords being used for describing components usually found in the one or more hardware devices 140, such as “CPU”, “DIMM” or the like. The description keywords can be keywords not being used for describing components usually found in the one or more hardware devices 140, such as “S/N”, “P/N” or the like. Additionally, the description keywords are extensible, such that the resource profile 120 can be adapted for varying standards and facilitate forming a new resource profile, to improve compatibility. Furthermore, such structure of the resource profile 120 makes it easy for maintaining, adding and updating the one or more hardware devices 140.

The hardware management and orchestration software 130 can be implemented as managing the one or more hardware devices 140 in a unified manner, to obtain the MAC address, the count and family of CPU/DIMM, S/N, P/N, monitoring information and other attribute information of the hardware, etc. In some embodiments, the hardware management and orchestration software 130 can be configured in the data center, such as in the rack. In some embodiments, the hardware management and orchestration software 130 can provide, for example, a RESTful API as its interface.

The one or more hardware devices 140 can be configured in the data center, and can comprise, for example, computing nodes, memories, switches, PDUs or the like. In some embodiments, a given one of the one or more hardware devices 140 can comprise logic units of, for example, computing nodes, memories, switches, PDUs or the like, constructed by the hardware management and orchestration software 130.

The database 150 can be configured in the data center, and can comprise, for example, a CMDB or other storage storing information of the one or more hardware devices 140. Any currently known or to-be-developed database techniques can be used to implement at least one part of the database 150. The scope of the present disclosure is not limited in this regard.

FIG. 2 illustrates a flow chart of a process or a method 200 for data center management according to embodiments of the present disclosure. In some embodiments, the process 200 can be implemented in the data center management system 100 for instance.

At 210, the infrastructure tracing processor 110 can obtain information of one or more hardware devices 140 used in the data center. The information of the one or more hardware devices 140 can comprise identification information describing identifiable attribute(s) of the one or more hardware devices 140. The identifiable attribute(s) indicated by or included in the identification information can uniquely determine one type of hardware device 140 or an individual hardware device 140. Examples of such identifiable attribute(s) include but not limited to the MAC address, the count and family of CPU/DIMM, S/N, P/N, the monitoring information and other attribute information of the hardware etc.

In some embodiments, the infrastructure tracing processor 110 can periodically scan the information of the one or more hardware devices 110. For example, the infrastructure tracing processor 110 can comprise a daemon process running periodically. The scanning cycle can be set as, for example, per minute, per hour, per day etc. The daemon process invokes the interface of the hardware management and orchestration software 130 to obtain the information of the one or more hardware devices 140, and then uses an algorithm to identify the exact hardware device 140 that will be added or updated into the CMDB according to the resource profile 120.

Alternatively, in some embodiments, a listener can be configured in the hardware management and orchestration software 130 considering the delay in the above scanning method. Once the hardware management and orchestration software 130 detects a change in the one or more hardware devices 140, the information of the one or more changed hardware devices 140 will be pushed to the infrastructure tracing processor 110. Such pushing method can be dependent on the implementation of the hardware management and orchestration software 130.

At 220, the infrastructure tracing processor 110 can identify one or more hardware devices 140 by matching the identification information with the resource profile 120. As stated above, the resource profile 120 records identifiable attributes of a plurality of types of hardware devices 140. For example, assuming that the identification information obtained at 210 comprises the MAC address. In this case, at 220, the type of the hardware device 140 can be determined by looking up a corresponding MAC address in the resource profile 120.

At 230, the infrastructure tracing processor 110 can update record(s) associated with the one or more hardware devices 140 in the database 150 of the data center using the obtained information. Generally speaking, the record or a part of the record associated with the hardware in the database 150 can be added, modified or deleted based on the obtained hardware information. The specific example will be elaborated with reference to FIG. 3.

Through the above process 200, the hardware device 140 can be automatically traced and updated to reduce error occurrences and improve efficiency, which make it possible for tracing and updating the hardware device 140 in the current large-scale data center.

FIG. 3 illustrates a flow chart of a process or a method 300 for updating a record associated with the hardware in a database using the obtained information according to embodiments of the present disclosure. In some embodiments, the process 300, for example, can be implemented at the infrastructure tracing processor 110. It should be understood that the process 300 can be regarded as a specific implementation of action 230 in the process 200.

At 310, the infrastructure tracing processor 110 determines whether at least one part of the information obtained at 210 is included in the record(s) associated with the one or more hardware devices 140 in the database 150 of the data center. If the at least one part of the obtained information is included in the record(s), the process 300 proceeds to 320. In another aspect, if the obtained information is excluded from the database 150, the process 300 proceeds to 330, at which the infrastructure tracing process 110 adds the at least one part of the obtained information into the record(s) associated with the one or more hardware devices 140 in the database 150.

At 320, the infrastructure tracing processor 110 determines whether at least one part of the obtained information matches corresponding content item(s) of the record(s) associated with the one or more hardware devices 140 in the database 150. If the at least one part of the obtained information and the corresponding content item(s) are determined to be matched, the infrastructure tracing processor 110 maintains the corresponding content item(s) of the record(s) associated with the one or more hardware devices 140 in the database 150 unchanged. In another aspect, if the at least one part of the obtained information and the corresponding content item(s) are determined to be mismatched at 320, the process 300 proceeds to 340.

At 340, the infrastructure tracing processor 110 determines whether the corresponding content item(s) of the record(s) associated with the one or more hardware devices 140 in the database 150 is/are included in the obtained information. If the corresponding content item(s) is/are included in the obtained information, the process 300 proceeds to 350, at which the corresponding content item(s) of the record(s) associated with the one or more hardware devices 140 in the database 150 is/are updated based on the at least one part of the obtained information. For example, if the obtained information includes a fan speed of hardware device 140, which is mismatched with a fan speed of the hardware device 140 stored in the database 150, the new fan speed can be used to update the stored fan speed, such that the database 150 keeps the record of the hardware device 140 in the current data center.

In another aspect, if the corresponding content item(s) in the database 150 is/are determined to be excluded from the obtained information at 340, the process 300 proceeds to 360, at which the infrastructure tracing processor 110 removes the corresponding content item(s) from the record(s) associated with the one or more hardware devices 140 in the database 150. That is to say, it is considered at this point that because the one or more hardware devices 140 previously existed in the data center has been removed, the record(s) associated with the one or more hardware devices 140 can be removed from the database 150. In this way, the database 150 may be guaranteed to maintain the record of the one or more hardware devices 140 in the current data center.

The apparatus 400, for example, can be implemented at the data center management system 100, or can directly serve as the data center management system 100.

In other embodiments, the updating unit 430 is configured to, in response to corresponding content item(s) in the record(s) being excluded from the obtained information, remove the corresponding content item(s) from the record(s). In other embodiments, the updating unit 430 is configured to, in response to determining that at least one part of the obtained information mismatches corresponding content item(s) in the record(s), update the corresponding content item(s) based on the at least one part of the obtained information.
